Question

Select the correct answer.

What is 10^0 + 10^1 + 10^2 equal to?
A.
10,201
B.
120
C.
111
D.
110
E.
100

Answer 1

C. 111

Explanation:

10^0 is 1 because of the exponent rule for 0 which is x^0 = 1, 10^1 would be just "10" and 10^2 would be "10x10" which is 100, adding these up would be 1 + 10 + 100 which equals 111

Answer 2

Let's see

• 10^0=1
• 10^1=10
• 10^2=100

Now

`\\ \rm\rightarrowtail 10^0+10^1+10^2`

`\\ \rm\rightarrowtail 1+10+100`

`\\ \rm\rightarrowtail 111`
